ABSTRACT:
A monitor and indicating circuit for an electric appliance detects the absence of the energization voltage for the appliance exceeding a predetermined threshold and provides a brilliant flash from a xenon lamp which is visible from great distances. The circuitry is contained within a sealed housing and includes a self-contained battery supply and attachable to a fence post. The circuit employed is specifically designed to conserve battery power by controlling the flash frequency and the charging time for the storage capacitor used with the xenon flash tube.
